Counter weight connection structure of counter weight testing device of abnormal environment of oil hydraulic cylinder

Abstract

The invention provides a counter weight connection structure of a counter weight testing device of an abnormal environment of an oil hydraulic cylinder. The counter weight connection structure is characterized by comprising a counter weight body connection plate connected with the bottom of a counter weight body, a bracket connection seat, and an inner connection structure arranged between the counter weight body connection plate and the bracket connection seat, wherein the inner connection structure comprises a right side connection plate arranged at the right side of the counter weight body connection plate; a bottom connection plate is arranged at the lower part of the right side connection plate; the bottom connection plate and the right side connection plate are hinged; the other end of the bottom connection plate is connected with the counter weight body; a connection column and a decompression spring are arranged at the upper part of the bottom connection plate; the upper end of the connection column is connected with the counter weight body. The counter weight connection structure of the counter weight testing device of the abnormal environment of the oil hydraulic cylinder, provided by the invention has the beneficial effects of simple structure, convenience for utilization and accuracy in testing direction linkage; testing data is accurate, and the device is suitable for testing the oil hydraulic cylinders with various types.

Description

technical field [0001] The invention relates to a test device, in particular to a connection structure of a counterweight body of a test device for a counterweight in an abnormal environment of an oil pressure cylinder. Background technique [0002] At present, the hydraulic cylinders suitable for the cabs of heavy trucks have to go through tests and counterweight experiments to determine the suitable weight and pressure of the hydraulic cylinders after the production is completed to ensure the suitability of the hydraulic cylinders. The existing counterweight connection structure arranged between the counterweight and the bracket has problems such as inflexible use and inaccurate multi-directional test data, which directly affects the test data and use safety of the hydraulic cylinder. Contents of the invention [0003] The object of the present invention is to provide a counterweight body connection structure of a counterweight test device for an abnormal environment of ...
